Piljiiladel hia, Pennsyl ania, have invented certain 'mprovements in Truck-Unloading Devices, of which thefollowingis a specification, l

the present instance this'dust collector consists of a chamber 0' connected to a hopper a by a series of fabric fines c; the meshes of the fahiiclgtling such that the air will readily pass th'erethrough, but the dust be retained therein.

The frame :ofrthe truck is made as clearly shown in Fig. 3 the Ways for the trays being made of angle bars f andthese angle bars are turned in .at one end f .to formstops for the trays s, sothatwhen the track is tilted with the frameithe trays \vil'l remain in their slideways, but the cakes of it carried by the trays will be. discharged.

As illustrated in Fig.2, the truck has two sets of trays and it will be understood that the construction of the truck and the arrangement of the trays may be modified ac cording to circumstances.
